In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel SA573 structural steel Grade 65 plate online is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15~40mm during oil quenching. When the hardness is HB174~229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

The mode of iron and SA573 structural steel Grade 65 plate online steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of SA573 structural steel Grade 65 plate online steel logistics.

SA573 structural steel Grade 65 plate online, Hot-rolled steel coils are made of steel billets, which are made into strip steel by the rough rolling mill and the finishing mill after heating. The hr steel strip from the rolling mill behind the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil will undergo different processes according to the different needs of users, and is processed into steel plates, flat coils and slit steel strip products.
